The Master's program in Philosophy is open to students of all disciplines. It is not restricted to students who have already completed a Bachelor's degree in the subject. 

When you apply to a Master’s program in Germany, universities will usually expect you to have an academic degree in a related discipline. For the subject of Philosophy, and especially the interdisciplinary courses, this can vary from program to program. Relevant first degrees are often from the disciplines of Philosophy, Economics, Political Science, Law, Life Sciences or STEM subjects. For most programs, entrance tests or interviews are not part of the admission process, students must simply submit required documents. In addition to standard certificates (e.g. first degree certificate, a transcript of records, a language certificate), a CV and a letter of motivation are typically required.
